From: Eric Schmidt leu242 at yahoo.com> on 2005.07.12 at 10:50:02(13170)Has anyone evr come across variegated Xanthosoma
sagittifolium or Philodendron bipinnatifidum? Both are
common here in Florida. Xanthosoma sagittigolium
'Albomarginatum Monstrosum' can be found but I am
interested in a variegated form of the huge leaf
specimens (which might be X. robustum) that are
growing in many yards.

I do believe that what you are seeing and ID`ing as varigated Xanthosoma are
mainly a varigated form of Alocasia macrorrizos, not Xanthosoma. The
common plant sold as Xanthosoma 'albo marginata' I believe is actually an
unidentifed species of true Xanthosoma, at least according to Dr. Goncalves,
who is perhaps one of the leading expert on this group. It was named as X.
atrovirens by Deni Bown in her book, which I believe is also an error.
The species of Xanthosoma w/ the 'frills' under the leaf blade is
also an as-yet unnamed species without a 'good' scientific name. It too
has been in cultivation for a LONG time, I have it in a book from Brit.
Guiana from 1927.
I have not seen a varigated P. bipinnatifidum (P. 'selloum') as yet, nor a
var. P. evensii or P. xanadu.

Good luck, and keep us informed!

Good Growing,

Julius.

I had a look at the photo, and do not believe this is X.
sagittifolium/robustum. The leaf tissue at the sinus of the rear leaf
lobes is full almost to the point of juncture w/ the petiole, P.
sagittifolum/robustum has a naked area at this point. If I had to guess,
I`d have to say that the plant shown is a cultivar/selection of the one we
were discussing, the X. 'albo-varigatum monstrosum' or whatever cock-a-many
name it is being called, the one w/ the little 'cups' at the leaf-tips.
The other species of Xanthosoma that I have grown which also has this sinus
full to the base, very like the one in the photo, is one that grows from
tubers you can sometimes buy at Cuban/Latin stores called 'malanga
amarillo', or 'yautia amirillo'. To me this is interesting, as Deni Bown
equates and actually calls both of these plants by the same scientific name,
X. atrovirens.
I`d be interested in hearing any other opinions.

I have quite a few different versions of the ones known as atrovirens or
'pocket plant' in Florida. This one doesn't resemble those very much but
does look like the large grocery store malangas. I hate getting stuck with
just a cock-a-many name.

I have some large variegated Xanthosomas that look like sagittifolium to
me. Photo posted in IAS ID center.
